Speed

  • speed can change if it enters a new medium
  • if you assume that waves are traveling at a constant speed , then the wave length is inversely proportional to frequency
  • speed= wave length X frequency

Wavelength

• They can be measured from one point of a wave to another
• The point between two waves.
• Increasing the waves frequency decreases its wavelength

Frequency

  • is the number of complete cycles that pass a point in a given time.
  • Frequency is measured in cycles per second (c/sec) or Hertz (Hz)
  • The waves frequency equals the frequency of the vibrating source producing the waves

Amplitude

• A wave that is displaced from a resting position.
• The more energy a wave has, the greater its amplitude is.
• Ex. When you drop s pebble into a pond the wave is not very big, but when you jump into the water your wave is bigger.
